DOOR HOLDER.

Application filed November 2, 1923. Serial No. 672,275.

swung open and hold the door open by t'rictional means until the jointof the toggles is broken.

The object of this invention is to provide a few parts but efficient andeasy latching and also an easy intentional releasing of the stop by anupsetting oi the alignment of the tog gles.

My invention is illustrated in the accompanying drawings in which Figure1 is a perspective view of the holder holding a door open. Figure 2 is asection showing the holder on a door in open and in closed position.Figure 3 is a perspective view or part of one of the toggles and Figure4 is a crosssection taken on line 4- l in Figure 2.

In the drawing, 10 indicates the door frame and 11 indicates the doorwhich are equipped with a door holder comprising a toggle 12 and atoggle 13 which are hinged together as at 1 1-, this hinge being shortof one end of the toggles so that one toggle has a projecting end 15.The toggle 12 is fastened to the door Frame so that it can swing. In thedrawing, this fastening consists of a pivot 16 which secures the toggle12 to a plate 17 fastened by screws 18 or other means, to the upper partof the door frame.

The toggle 13 is pivoted to the door as by means 01"? the bracket 19 towhich it is secured by a pivot 20. The projecting end oi: the toggle 12has a stud'21 which preferably has a roiznded bottom surface, itsprojecting part being toward the toggle 13. The toggle 13 has a hole orother form of recess 22 which is placed so that it receives the stud 21when the r": are aligned. On the toggle 13 adja centto the hole 22, andin the path oi the stud when it is swung over the toggle 13, is a groove23. This groove is shalloweron the end adjacent to the hole 22 anddeeper at its outer end 24 so that, as will be evident trom Figure 4,when the toggles are being swung together and the stud 21 engages thegroove 23, the groove exerts a cam action and the necessary distortionof the toggles 1s easlly accomplished to the point where the stud 21snaps into the hole 22. A stop 25 usually formed integral with thetoggle 13, prevents any excessive swinging oi the door forcing thetoggles beyond'their aligned position.

To provide for a ready closing of the door by breaking the joint of thetoggles, I fasten the chain 26 to the shorter toggle 13 on the sideopposite that on which the stop 25 is located and run this chain throughan eyelet 27 on the door which is on the same side of the toggle '13 asthe fastening 28 of the chain so that when the handle 29 is pulled, thetoggle 13 is not only pulled toward the door and the door toward thetoggle, but the toggle is pulled downward enough to distort it slightlyto enable the rounded face of the stud 21 to ride easily into the groove23 and then once the alignment of the toggles has been brokenythe doorcan be easily swung to closed position in which the toggles assume theposition shown in full lines in Figure 2.

It will be evident that minor changes such as a pulley in place of theeyelet 27 and other slight imodifications, can be introduced withoutdeparting from the scope of the invention;

I claim:

The combination of a door casing and a door, with an arm pivotallysecured at one end to the door, and a second arm pivotally secured atone end to the casing, the arms being horizontally disposed the arn'isbeing pivoted together so that onehas a short proj ecting end, a stud insaid end, the other arm having a hole to receive the stud and having agroove leading to the hole, said groove being deepest at its outer endand shallowest at the hole to cause a cam actionto cause a slightdistortion of the arms when the stud passes through the groove to thehole, and a chain secured to the arm having the groove and near saidgroove and is slidably secured to the door so that when the chain ispulled the arms are slightly distorted and their align ment broken andthe closing of the door thereby initiated.

In testimony that I claim the foregoing, I have hereto set my hand, this12th day or October, 1923.

' HAROLD S. WILSON.
